Frequently Asked Question:

What is coal tar pitch?

Coal-tar pitch is a thick black liquid that remains after the distillation of coal tar. It is used as a base for coatings and paint, in roofing and paving, and as a binder in asphalt products.

What is roof pitch made of?

Roof pitch is comprised of two numbers in the form of a ratio. You’ll see it expressed either with a slash – 5/12 or 8/12 – or with a colon – 5:12 or 8:12. Either way, the numerator and denominator work together to tell you the pitch of the roof. The numerator refers to the height of the roof.

What is pitch used for on a roof?

Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge). There are two suggested ways to measure a roof pitch.

How long does a coal tar pitch roof last?

Coal-tar roofs are reported to average 25 years of life, and some have been known to last more than 50 years with proper maintenance and surface restoration.

Is pitch similar to tar?

Tar and pitch are often used interchangeably. However, pitch is considered to be more solid whilst tar is considered to be more liquid. Asphalt Asphalt is a sticky, black and highly viscous liquid or semi solid that is present in crude petroleum and in some natural deposits sometimes termed asphaltum.

What are the types of roof pitches?

There are two types of roof pitches: high-pitched and low-pitched. Low-pitched roofs were most popular in the 1960s. These roofs appear to be flat, however, they tend to have a 1/12 pitch. Low-pitch roofs still have a bit of a slope to drain the water.
